DEVICE FOR DIPPING STOCK.

Specification of Letters Patent.

. Patented May 19, 1908.

Application 1ed July l, 1907. Serial No. 381,811.

To all whom it may concern.'

Be it known that I, WILLIAM K. CRAP- NELL, citizen of the United States, residing at Joy, in the county of Mercer and State of Illinois, have invented certain new and useful Improvements in Devices for Dipping Stocks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a device for use in dipping stock.

The object of the invention is to provide a simple and convenient arrangement whereby hogs and cattle and other stock may be driven into it and precipitated therefrom into the usual dipping tank used for such purposes.

It is well known that farmers and even dealers in stock very often find it necessarT to treat the stock toa disinfecting solution for destroying disease germs and the like, and so far as my knowledge goes it has been customary heretofore to dip the stock by driving them up a run and then pushing them into the tank containing the solution. As this work is very laborious and unsatisfactory I have devised a device by which very little work is necessary and by which, also, a great many animals can be treated in much less time than heretofore.

In the appended drawings Figure l is a side elevation of my device surmounting a dipping tank. Fig. 2 is an end view of the same. Fig. 3 is a perspective view of a portion of the device. Fig. 4 is a view of the bottom. Fig. 5 is a perspective view of a portion of the device. Fig. 6 is a side view of those parts shown in Fig. 5.

A re resents a tank for containing the dipping so ution, above which is mounted an inclosure having two sides and an end represented by B and O, respectively, the other end being open as shown in Fig. 3 at which terminates a run-way shown in Fig. 1 at D and which, though not so shown, may connect with the stock pen. The bottom of the inclosure consists preferably of two doors E E adapted to open downward as indicated in broken lines in Fig. 2 and as shown clearly in Fig. 3. These doors are hinged at F to the lower members of the sides B as in Fig. 5 wherein one-half of the hinge of one of the doors is secured on the top of one of said members, while the other portion of said hinge is attached to the door substantially in the position shown. One of the doors has a cleat G secured thereto near each end as shown in Fig. 4 one end projecting beyond the free edge of the door and extends beneath the other door, the purpose of which will be described presently.

Secured on one of the lower side members are two brackets H to one of which is pivoted a hand lever J, the other having pivoted thereto a short lever K, the upper end of the latter having connection with the said lever J by means of a rod L. The lower ends of both levers are bent at right angles and. extend inward within notches M in the said bottom member as clearly shown in Fig. 5, said bent ends adapted to extend slightly beneath one of the doors so as to support the free ends of the cleats G already described. At one end of the inclosure is a rock-shaft N having suitable bearings upon the lower members of the sides B, and one end of said shaft has an upturned arm O connected to the lever J by means of a rod or link I. Said shaft also has extending inwardly therefrom near each end a projection or pin Q as shown in Fig. 4. However, when the stock within the tank is entirely cleared from the vicinity of the doors, the lever during its movement toward its normal position for supporting said doors will rock the shaft N and the latter will carry the pins Q downward past the line of the hinges thus freeing the doors and allowing the springs, which are under tension, to at once raise and close the doors so that the arms G attain the proper position to be engaged by the levers. It is to be understood that the action justl described takes place the moment the pins are moved slightly below the hinge line so that the doors are in place before the bent end of the levers reach the position for supporting them. Fig. l shows the extreme lower position of the pin Q when the lever J is in the position shown in full lines but as just intimated merely a slight movement of the pins in a downward direction is suflicient to release the doors since the axis of the shaft carrying them is substantially at the same height as the pivots of the hinges. The operator can, of course, move the lever only artially to release the doors and then compliete the movement thereof after the latter are at rest. The springs of the door shown at the right of Fig. 2 i. e. the door that is su ported by the projecting ends of the arms G), is normally under greater tension than the opposite one whereby its doors will close before the door having the said arms G can rise to position. This insures the proper relative position of the parts during and after the closing movement. as shown in Fig. 2, is provided with a door B having a suitable fastening at B2 which door provides for allowing the operator to reach the interior of the inclosure and the tank when necessary for any purpose.

I do not confine myself to the particular manner in which the doors are supported since any other means may be used for that purpose and I may use but one lever instead of two for supporting the doors. Furthermore, I may use other means by which to hold the doors in an open position and may also use means other than the springs for the closing operation.

Having thus described my invention, I claim:

1. Adevice for dipping stock comprising an inclosure, a bottom therefor adapted to open downward by weight thereon, coacting means for supporting the bottom and manually operated to release the same, and means for returning the bottom to its normal closed position.

2. In a device for dipping stock, an inclosure, a bottom therefor adapted to open downward by weight of the stock thereon, means for automatically raising the bottom to its normal closed position, and means for supporting the bottom in a closed position and manually operated means by which to release the same.

3. In a device for dipping stock, an inclosure, a bottom therefor adapted to open downward by weight of the stock thereon, means in connection with the bottom and placed under tension by the opening movement thereof for positively raising and closing said bottom, means for positively holding the bottom in the open position, and other coacting means for positively supporting the bottom when raised and closed.

4. In a device for dipping stock, an inclosure, a bottom for the same adapted to open downward by weight imposed thereon, coacting means for supporting the bottom in its closed position and manually operated to permit said bottom to open, and means operated by the first described means for holding the bottom in its open position, and means for returning the bottom to its closed position.

5. In a device for dipping stock, an inclosure for the stock, a fluid tank-beneath the inclosure, a bottom for substantially the entire inclosure, said bottom adapted to open downward to precipitate the stock into the tank, means for supporting the bottom in its closed position, means for supporting the rst said means and manually operated to release the same substantially as described.
